In the process of bonding and positioning the bracket 50 by the known orthodontic auxiliary bonding guide plate, the bracket 50 needs to be fixed on the encircling bracket 20 through the water-soluble adhesive 60, then the orthodontic auxiliary bonding guide plate and the bracket 50 are transferred onto the teeth of a patient together, the bracket 50 can be bonded on the teeth more firmly by pressing the guide plate, then the guide plate is separated from the bracket 50 when the bracket 50 is bonded on the teeth firmly, so as to finish the operation of the bracket 50, through the above process, the embodiment can improve the fault tolerance of the bracket in clinic and reduce the error correction cost by setting a gap in advance and enabling the bracket 50 to abut against the encircling bracket 20, so that after the bracket 50 abuts against the encircling bracket 20, the bracket 50 can be positioned on the unique position of the encircling bracket 20 through filling the water-soluble adhesive 60 in the gap between the bracket 50 and the encircling bracket 20, that is to say, the accurate positioning of the bracket 50 on the encircling bracket 20 can be realized; in addition, as can be seen from the above, in order to stably adhere the bracket 50 to the teeth, the orthodontic auxiliary adhesive guide plate needs to be pressed, and when the orthodontic auxiliary adhesive guide plate is pressed, in order to improve the pressing stability of the orthodontic auxiliary adhesive guide plate, the orthodontic auxiliary adhesive guide plate can be more stably contacted to the teeth through a larger size, so that the bracket 50 can be properly fixed through the orthodontic auxiliary adhesive guide plate under the condition of a certain supporting surface, therefore, the inner face 101 of the jaw pad 10 of the orthodontic auxiliary adhesive guide plate is embedded with the teeth closing surface 401, and the orthodontic auxiliary adhesive guide plate can be prevented from being shifted in the pressing process by the embedding manner.
As shown in fig. 3, in one embodiment, the water-soluble glue 60 is a double paste (hydroxyethyl methacrylic acid), which is formed by combining resin monomer, polymer, filler, ethylenediamine, epoxy resin and hydroxyethyl methacrylic acid as main materials, and can be automatically cured by natural light irradiation, meanwhile, according to development requirements, the double paste loses bonding capability after impact of water impact, and in the inherent state of the double paste, the thickness of the film is less than or equal to 25 μm, the compressive strength is greater than or equal to 50MPa, and the water-soluble glue 60 bonds the bracket 50 with the guide plate part surrounding the bracket 20, so as to ensure firm no displacement between the bracket 50 and the orthodontic auxiliary bonding guide plate, and further ensure 1:1 reduction of the position of the bracket 50 determined in the computer during transfer.
In one embodiment, since different batches of brackets 50 may have errors during production, a certain gap value is required for fault tolerance before surrounding brackets 20 and brackets 50, and thus a gap value comparison experiment is performed during background design, and the experimental method and result are as follows:
5 groups of brackets 50 with the same brand and the same type and different batches are selected for carrying out the bonding test of the same model, 4 gap intervals of 0mm, 0.01-0.03mm, 0.03-0.05mm and 0.05-0.07mm are respectively arranged for the brackets, and bonding results are shown in a table:
as shown by the result data, when the gap between the bracket 50 and the surrounding bracket 20 is larger than 0.05mm, the transfer precision of the bracket 50 is the worst, the gap interval between the bracket 50 and the surrounding bracket 20 is the best between 0.03mm and 0.05mm, and the transfer precision of the bracket 50 and the surrounding bracket 20 is better than that of the bracket 50 without the gap, therefore, the transfer precision of the clinical bracket 50 can be ensured to be controlled within 0.1mm by selecting the gap between the bracket 50 and the surrounding bracket 20.
In one embodiment, since the accuracy of the clinical model collection & the batch produced by the printer are prone to error, if the portion attached to the tooth surface 401 is completely attached to the tooth surface, the fault tolerance rate is reduced, and the clinical adhesion accuracy is affected, and thus, the gap value comparison experiment is performed in the background design, and the experimental method and the result are as follows:
under the condition that model data and printer parameters are constant, 3 groups of gap intervals are selected for testing, namely 0-0.05mm, 0.05-0.1mm and 0.1-0.15mm, the 3 groups of data are used for respectively bonding 10 groups of different models, and the gap values and bracket 50 transfer precision pairs are as shown in the table:
as shown in the result data, when the gap between the inner surface 101 of the jaw pad 10 and the teeth-engaging surface 401 is greater than 0.1mm, the accuracy of the bracket 50 is the worst, and the gap between the inner surface 101 of the jaw pad 10 and the teeth-engaging surface 401 is the best between 0.05 and 0.1mm, so that the gap between the inner surface 101 of the jaw pad 10 and the teeth-engaging surface 401 is 0.03 to 0.05mm, and the accuracy of the bracket 50 is controlled within 0.1mm.
As shown in FIG. 1, in one embodiment, since bracket 50 is bonded to the tooth by resin, the process is: the bracket 50 installed in the encircling bracket 20 is coated with resin, and then the bracket 50 coated with resin is adhered to the teeth, and the bracket 50 is fixed on the teeth, so that the bracket 50 is separated from the orthodontic auxiliary adhesive guide plate, and the resin flows onto the orthodontic auxiliary adhesive guide plate to influence the separation of the orthodontic auxiliary adhesive guide plate because the bracket 50 is small and easy to cause excessive coating of the resin by doctors, the connecting rod 30 is vertically arranged at one end of the jaw pad 10, the vertical connecting rod 30 is arranged to support the encircling bracket 20 on one hand, and the vertical connecting rod 30 is arranged to enable enough overflowing space of the resin coated on the bracket 50 to avoid the adhesion of the orthodontic auxiliary adhesive guide plate with the tooth surface when the orthodontic auxiliary adhesive guide plate is pressed.
As shown in fig. 4, in an embodiment, a pressing columnar protrusion 70 is disposed on the outer surface of the jaw pad 10 in the direction of the occlusal surface 401, wherein the outer surface of the jaw pad 10 is located on the opposite surface of the inner surface 101 of the jaw pad 10, that is, if the inner surface 101 of the jaw pad 10 is used as the front surface, the outer surface of the jaw pad 10 is the back surface, the pressing columnar protrusion 70 is used as a pressing mark point, and both anterior teeth and posterior teeth are distributed, and the pressing columnar protrusion 70 is disposed on the outer surface of the jaw pad 10 in the direction of the long axis of the tooth, so that a doctor can quickly recognize the finger during clinical operation to assist the pressing of the orthodontic auxiliary adhesive guide plate, the position where the pressing columnar protrusion 70 is disposed is the pressing center point, the error of transferring the bracket 50 due to the fact that the pressing is not in place when the adhesive bracket 50 is pressed can be reduced, and the accuracy of transferring the bracket 50 is further assisted.
As shown in fig. 4, in one embodiment, a lingual side rocker 80 is disposed on an end of the jaw pad 10 near the surrounding bracket 20, and the lingual side rocker 80 is distributed on the full dentition for assisting the orthodontic auxiliary adhesive guide plate to be better detached from the bracket 50.
As shown in fig. 5, in one embodiment, since the area of the cross-sectional area of the front occlusal surface is smaller than that of the rear occlusal surface, and the cross-sectional area of the occlusal surface is a horizontal line, especially at the forefront front teeth, if a single guide plate is used for assisting positioning, the problem that the front teeth are easy to adhere and shake is clinically caused when the front teeth are adhered by the single guide plate auxiliary bracket 50, and in this embodiment, the lingual support bar 90 is arranged on the orthodontic auxiliary adhesive guide plate of the front teeth, that is, on the end of the jaw pad 10 of the orthodontic auxiliary adhesive guide plate, which is far from the encircling bracket 20, the lingual support bar 90 is just complemented in the vertical direction and is adhered to the jaw pad 10, so that the adhering area of the orthodontic auxiliary adhesive guide plate of the front teeth area and the front teeth is improved, and the adhesion of the front teeth area position becomes more convenient and accurate.
In summary, the orthodontic auxiliary adhesive guide plate includes a jaw pad 10 and an encircling bracket 20, wherein the inner face 101 of the jaw pad 10 is embedded with the teeth engaging surface 401 of the three-dimensional model of teeth, and a gap is formed between the inner face 101 of the jaw pad 10 and the teeth engaging surface 401; the encircling bracket 20 is arranged at one end of the jaw pad 10, the encircling bracket 20 is used for propping against and fixing the bracket 50, and a gap is reserved between the encircling bracket 20 and the bracket 50; the water-soluble glue 60 is applied to the gap between the surrounding bracket 20 and the bracket 50 for fixing the bracket 50 against the surrounding bracket 20 to the surrounding bracket 20.
